ELECTRICAL RESPONSE OF ANODIZED ALUMINUM LAYERS TO SHOCK-WAVE COMPRESSION

The electrical output which is obtained from an anodized aluminum layer during shock-wave loading has been studied as a function of shock stress, sample area, shock propagation direction, and temperature history. The dependence of the electrical response on these variables is shown to be consistent with an electret-like behavior of the anodized layers. A sample macroscopic model based on this behavior is used to predict the features of the electric output. © 1969 The American Institute of Physics.
